DOW FILMTEC™ SFP-2880 Ultrafiltration Modules # 10,300 แกลอนต่อวัน (10300 GPD)

The SFP series of the DOW ultrafiltration modules are built with robust outside-in PVDF fiber technology. The hollow fibers feature high clean-ability, low chemical consumption, high recovery, and a superior combination of mechanical properties and chemical resistance. It offers customers a proven product with a long list of installations world-wide.

DOW ultrafiltration SFP-2880 offers the highest membrane active area within the SFP series and is an excellent choice for large installations.

Advantages

• Excellent removal of colloids, particles, and bacteria
• Low chemical consumption
• Ability to treat challenging feed water with limited pretreatment
• High chemical-resistance PVDF that allows aggressive chemical use for treating challenging water when needed
• Mechanically strong fibers enabling long module life

Important information

Proper start-up of a UF system is essential to prepare the membranes for operating service and to prevent membrane damage. Following the proper start-up sequence also helps ensure that system operating parameters conform to design specifications so that system water quality and productivity goals can be achieved. Before initiating system start-up procedures, membrane pretreatment, installation of the membrane modules, instrument calibration and other system checks should be completed. Please refer to the product technical manual.

Operation guidelines

Avoid any abrupt pressure variations during start-up, shutdown, cleaning or other sequences to prevent possible membrane damage. Flush the UF system to remove shipping solution prior to start up. Remove residual air from the system prior to start up. Manually start the equipment. Target a permeate flow of 60% of design during initial operations. Depending on the application, permeate obtained from initial operations should be discarded. Please refer to the product technical manual.

General information

If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty (Form No. 795-00027) will be null and void.
To prevent biological growth during system shutdowns, it is recommended that preservative solution be injected into the membrane modules.

Specifications

Features

The DOW™ Ultrafiltration (UF) modules are made from high strength, hollow fiber membranes that have excellent features and benefits:

• 0.03 μm nominal pore diameter for removal of bacteria, viruses, and particulates including colloids to protect downstream processes such as RO
  
  
• PVDF polymeric hollow fibers for high strength and chemical resistance allows long membrane life
  
  
• Hydrophilic PVDF fibers for easy cleaning and wettability that help maintain long term performance
  
  
• Outside In flow configuration for high tolerance to feed solids that help reduce the need for pretreatment processes
  
  
• U-PVC housing, helping to eliminate the need for costly pressure vessels

This module is an ideal choice for systems with capacities greater than 50 m3/hr (220 gpm). Larger and longer, 8 inch diameter and 80 inch in length, together with an increase in packing density of 10,000 fibers, this module offers the highest effective membrane area of the DOWTM Ultrafiltration modules. The 2880 contributes to a more economical membrane system design.

DOWTM Ultrafiltration Modules can be used for a wide variety of treatment applications such as surface water, seawater, industrial wastewaters, and secondary effluent wastewater.
